SPECIFICATION forming part of Letters Patent No. 452,801, dated May 26,1891.

Application filed August 23, 1890. Serial No. 362,882, (No model.)

To all whom it may concern.-

Be it known that I, CHARLES E. PATRIC, a

citizen of the United States. residing at Springfield, in the county ofClark and State of Ohio,

5 have invented certain new and useful Improvements in Grain-Drills, ofwhich the following is a specification.

My invention relates to improvements in grain-drills; and the object ofmy invention I is to simplify the constructions heretofore employed.

My invention consists in the various constructions and combinations ofparts hereinafter described, and set forth in the claims.

In the accompanying drawings, which form a part of this specification,Figure 1 is a plan View of agrain-drill embodying my invention, thehopper being shown removed and some of the parts broken away. Fig. 2 isa sectional elevation view of the same. Fig. 3 is an elevation showing aportion of the raising and lowering devices and the means for throwingthe operating mechanism into and out of gear. Fig. 4: is a sideelevation, partly in section, of the same. Fig. 5 is a detailed view ofa portion of the same. Fig. 6 is a top view of the clutch device and themeans for operating the same. Figs. 7 and S are details showing theconstruction of the drag-bars and the means employed for shifting thesame to bring the shoes or hoes in double or single rank. Figs. 9, 13,and 14: are details of portions of the frame. Figs. 10 and 11 are frontand sectional views, respectively, of the axle-box. Fig. 12 is a detailof a portion of the liftinglever.

Like parts are indicated by similar letters of reference throughout theseveral views.

In the said drawings, A A represent the driving and carrying wheels onwhich the machine is supported and from which the power to drive thefeeding mechanism is derived.

B is the hopper, C C the frame, and D the tongue.

The frame O O, I construct of a single bar or piece of flat metal bentat right angles, or substantially so, at the front corners O and G withthe side rails or wings connected together near the rear ends of saidframe by a oross-barO Fin. 9 oreferablv of wood.

This

crossbar C is fitted at each end in a bearingplate 0 provided withprojecting flanges a, adapted to form a socket (1/, into which the bar 0is adapted to fit, one of which flanges (b is extended along the side ofthe bar C and adapted to receive two lateral bolts a which extendthrough the said bar and flange. The bearing-plate is also provided onthe opposite side with lateral flanges n. adapted to embrace the saidframe and hold the bar against lateral movement, a wood or lag screw abeing preferably extended through the frame and bearing-plate and intothe crossbar C thus firmly binding all the parts together.

The tongue D is secured at its inner end to the cross-bar 0 by a plateOlwhich platehas projecting ears Z), adapted to receive a fastening-boltb, which passes through the said cars and the said tongue. The tongue Dextends forward from the cross-bars 0 passing over the front rail of theframe O.

Secured at one end to the tongue D and at the other to the front rail ofthe frame O is a bearing-support or hanger E, having bearings d for therotating bars E E which extend through the frame near the front thereofand are jonrnaled at each end in suitable bearings attached to saidframe. These bars are provided at suitable intervals with projectingarms or fingers cl (Z each having a projecting boss (i on which arejournaled the ends of the drag-bars E attached to the hoes The rotatingbars E E are preferably made square, the arms d d being correspondinglyformed to fit over the same. The dragbars E are bifurcated at theirforward end and provided with openings adapted to slip over the lugs orprojections on the arms a? one of said arms being employed for each forkof each drag-bar. The drag-bars are formed with sufficient resilience topermit them to be spread apart and forced over the lugs d on which theyare held by the elasticity or 5 resilience of said bars. Itwillbenoticed that the drag-bars while being placed in position arespread, so as to fit over the outside of the arms (F, the resilience ofsaid bars being adapted to close the forks thereof together. me Anyweight or longitudinal strain on the dragbars tends to close them stillfarther, so that ation tends to close the outer ends of said I of theoperator.

drag-bars more firmly against said arms and on the lugs or projections dthus insuring them against accidental displacement.

Located on each of the bars E E is a gearsegment F and F thesegear-segments being preferably arranged at or near the centers of thebars and provided with hubs adapted to fit in the bearings 61 cl in thebearing support or hanger E. These gear-segments are each provided attheir extremities with a stop projection or lug 01 against which theteeth of the opposite segment are adapted to come, thus preventing afurther revolution of said gearsegments.

Motion is imparted to one of the bars E E through the medium of a leveror arm E to whichis attached a suitable operating-rod E, extended to aconvenient pointwithin reach A movement of one of the rods or'bars isimmediately transmitted to the other through the medium of thegear-segments F F Each alternate drag-bar is connected to the oppositerotating bar E or E the arms (1 d on said bars being arranged so thatwhen in the normal position the lugs d thereon stand in line, as shownin Fig. 2, the hoes or shoes E thus being arranged in single rank. Whenthe bars are rotated, the arms are thrown out in opposite directions,thus throwing each alternate hoe or shoe backward and forward, thusbringing them into double rank or zigzag.

The hanger or bearing-support E being connected directly to the tongue Dand to the frame 0, the parts are held firmly in their respectivepositions, while the strain is transmitted directly from the tongue tothe dragbars, the frame being thus relieved, permitting a light andflexible frame to be used.

To secure rigidity in the parts of the frame I preferably supplycorner-braces 0 extending from the front rails to the side wings, asshown in Fig. 1. It will be understood that the power to drive the drilland the operating parts is applied directly from the tongue D throughthe medium of the doubleand single trees D in the usual manner.

The power to drive the feeding mechanism is derived from theaxle A inany well-known manner, preferably by means of my improved changeableadjustable disk-wheel device, by means of which the speed of thefeed-shaft may be varied by shifting the pinion to different positions011 the disk-wheel in a wellknown manner. The wheels A A are normallyloose on the shaft or axle A, but are adapted to be connected theretoand revolve said shaft by the clutch device A arranged at each end ofthe axle in connection with the hubs of the driving-wheels A. Theseclutches A consist of a serrated clutch-collar 0, adapted to slidelongitudinally on the axle A, but connected thereto by a spline or inany other suitable manner, so as to cause said axle to revolvetherewith, a similarlyserrated face or collar 0 being provided on eachof the hubs of the driving-wheels. The clutches A are arranged justoutside of the axle-boxes A by which the axle A is supported andconnected to the frame C. The clutch-collar c is adapted to be held incontact with the serrated face 0 by small springs 0 which press againstsaid collar. The axlebox A is provided on each side of the mainaxle-bearing with small bearings 0 through which are adapted to slideconnecting-links 0 each provided at one end with a lateral projectingflange or hook cfladapted to engage in a peripheral groove 0 in theclutchcollar 0, these links 0 being arranged ateach side and parallelwith the axle A. Extending through a bearing A at right angles" to saidaxle and to said links, and preferably above the same, is a rock-shaft 0provided at one end with a hook-shaped projection 0 adapted to engagewith one of. the links 0 and provided at the other end with abellcranklever 0, one arm of which engages with the opposite link IMeans are provided for imparting motion to the bell-crank lever 0 andthus to the rock-shaft 0 thus producing a simultaneous movement of thelinks 0 which movement is transmitted to the clutch-collarc to withdrawthe same from the clutch-face c on the hub of the wheel A.

The axle-boxes A are each constructed in two parts, the bearing proper Abeing made separate from the main portion or frame. The bearing part ismade to fit loosely in an opening 'h, formed in a web or flange h. Thisweb or flange is provided with a lug or projection 7L2, adapted to fitin a notch or openin g h in an annular flange 7L with which the bearingproper is provided. By this arrangement the bearing proper is adapted toadjust itself to a limited extent within the main or frame portion, andthus prevent cramping the axle in assembling the parts. holds thebearing against end pressure from the wheels, while the lug orprojection prevents the bearing from turning in the outer or frameportion.

A lifting -bar G, extending transversely across the machine above thedrag-bars E furnishes the means for raising and lowering said drag-barsthrough the medium of stirrups G in a well-known manner. Thislifting-bar Gr is provided at each end with arms G pivoted to suitablebearing-supports G arranged on each side of the frame 0, the said armsbeing preferably connected to the lifting-bar at each end by a spline 6,formed in an opening in each of said arms, in which the end of saidshaft is adapted to fit, and a set-screw 6, adapted to pass through saidarm and bear against said bar. (See Fig. 3 for detail.) Each of the armsG is provided with a projecting stud 0 on which is journaled a conmeeting-link 6 which extends downwardly and is connected to thebell-crank lever e of The flange 71 the clutch-operating mechanismheretofore described. It will be seen, therefore, that as thelifting-bar G is raised or lowered to raise or lower the hoes or shoesmotion is imparted to the operating mechanism of the clutches.

The groove 0, in which the hook-shaped end of thelinks c engage, is madesufficiently wide to permit a limited movement of said links after theclutch-faces are in engagement. This permits a limited movement of thelifting-bar G sufficient to regulate the depth of the hoes or thepressure thereon without disturbing the contact of the clutch-faces.\Vhen, however, the lifting-bar G is raised sufficient to raise the hoesor shoes from the ground, the clutch faces are disengaged, thus throwingthe operating parts out of gear.

The motion for operating the liftingbar G is preferably secured from alifting-lever H, journaled in a suitable bearing in a ratchetstand H,secured to the frame 0 and connected to one of the arms The ratchetstandH is secured to the frame 0 and provided with a laterally-projectingflangef, arranged on the arc of a circle whose center is at the centerof the pivoted connection of the hand-lever H, said flange beingprovided with a series of notches f. Located in the end of the lever Hand extending across the same at right angles thereto is a latch fpreferably formed on the arc of a circle, pivoted at f to one side ofsaid lever and connected at its opposite end by a suitable connection fto a thumb-lever This latch f is provided with a projection f on oneside thereof, adapted to engage in the respective notches f of thesegmental flange f, a spring f arranged within the handle H, beingadapted to press said latch outwardly from the end of said lever, meansbeing thus furnished for holding the lever H and the lifting mechanismin any desired position. It will be seen that by the above constructionssimple mechanism is provided to accomplish the various adjustments ofthe machine. The feeding mechanism is adapted to be operated from eitheror both of the driving wheels, and

means are provided for automatically disengaging said wheels and thusthrowing the feeding mechanism out of gear when the shoes or hoes areraised. By the construction of the drag-bars and their connections,together with the frame, as described, a light, strong, and simpleconstruction is secured.
